Containers are a fundamental building block of Bootstrap that contain, pad, and align your content within a given device or viewport.
Containers are the most basic layout element in Bootstrap and are required when using our default grid system.
Containers are used to contain, pad, and (sometimes) center the content within them. While containers _can_ be nested, most layouts do not require a nested container.
Bootstrap comes with three different containers:
Container
, which sets a max-width
at each responsive breakpoint.type="fluid"
, which is width: 100%
at all breakpoints type="{breakpoint}"
, which is width: 100%
until the specified breakpoint The table below illustrates how each container's max-width
compares to the original Container
and type="fluid"
across each breakpoint.
Extra small <576px | Small ≥576px | Medium ≥768px | Large ≥992px | X-Large ≥1200px | XX-Large ≥1400px | |
---|---|---|---|---|---|---|
container | 100% | 540px | 720px | 960px | 1140px | 1320px |
container-sm | 100% | 540px | 720px | 960px | 1140px | 1320px |
container-md | 100% | 100% | 720px | 960px | 1140px | 1320px |
container-lg | 100% | 100% | 100% | 960px | 1140px | 1320px |
container-xl | 100% | 100% | 100% | 100% | 1140px | 1320px |
container-xxl | 100% | 100% | 100% | 100% | 100% | 1320px |
container-fluid | 100% | 100% | 100% | 100% | 100% | 100% |
Our default Container
class is a responsive, fixed-width container, meaning its max-width
changes at each breakpoint.
Responsive containers allow you to specify a class that is 100% wide until the specified breakpoint is reached, after which we apply max-width
s for each of the higher breakpoints.
For example, type="sm"
is 100% wide to start until the sm
breakpoint is reached, where it will scale up with md
, lg
, xl
, and xxl
.
Use type="fluid"
for a full width container, spanning the entire width of the viewport.
